Toall whom it may concern:

Be it known that 1,.SAMUEL (:l; G083, a "citizen of the United States, residing at .G-lencoe, in the county of Cook and State of Illinois; have -invented certain new and useful Improve:nents in Mechanism for Pro dncing aFoldcd- Product, of which the fol: 'filowingv is a specification, reference being had to the accompanying drawings. r 0" -My invention relates to new and improved mechanism for producing a folded product. As is well-known, when product consisting of a ninnher of sheets is folded centrally, the folded product, especially when it -onsists of a considerable nninlieroit superposed sheets; will have the ed tes of the, inner -sheets parallel with the "fold projeeting heyondthe edges of the outer shoe this progression of projection increasing fromthe outer to the central sheets and from each side'. This results, of course, necessarily from the folding together centrally of a nnmher of sheets of the same length or widththat is to say, of the'same size measured at right angles to the fold! Itbecomes necessary, therefore, when such pamphlet, or similar folded product, consists ofa mun; her of leaves and when it is necessary to give particular care to its appearance, that it should be subsequently trimmed in order that the edges parallel to the. fold may be even and present a suitable appearance.

It. is the object of my invention to produce a product which will-do away with 5 this difficulty and which will not have to be trimmed after being folded, and also'to produce a new and improved mechanism for the production of the same.

illustration, shown as a single web, al though, of course, it n'iay consist of several webs superposed. The web or webs A pro' ceed from any suitable form of printing machine which ofitselt forms no part of my present invention and is, therefore, not shown. Passing between forwarding rollers 4 and 5-the web passes downward between cutting cylinders (3 and 7. The cylinder 6 isv provided with cutting knives 8- 1011 which cooperate with corresponding cutting hlocl-ts 12131ft15 on cylinder 7 to sever the Wtfl) or webs transversely. The knives S to 11. and, of course, the corresponding cutting blocks 12 to 15 vary progressively in their distance apart circumferentially of the cylinders so as to cut the web or Webs passing between the cylinders successively into progressively varying lengths during each rotation of the cylinder. In the form shown I have shown fonrcut-ting knives and four corresponding cutting blocks whereby, of course, jfour successive cuts will be made with each revolution of the cylinder. The

distance between the knives Sand 9 and blocks 12 and-13 isthe least circumferen tially of the cylinder, between 9 and 10 and 13 and 141 the distance is somewhat. greater, between 10 and 11 somewhat greater, and between 11 and 18 and 15 and 12 the greatest, whereby, of course, the web or wehs are with each rotation of the cylinder cut into four sheets or groups of sheets which vary progressively in Width transversely of the I proposed fold.

Of course it; will be understood that the number'of knives may be varied so that the cylinders may contain a greater or less nnm? her; in accordance with the demands, and general varying distances will'depend upon the thickness of the paper to he used or it several webs are usedupon the number of webs. After being severed the sheets are seized successively by a collecting cylinder 16 e en is of any well-known form and f ,DilOll and which, in the form shown, by any well-kn0wn mechanism. to superpose the four cuts produced by each rotation of the cutting cylinders npon'one another on the, collecting cylinder before they are released. The collecting cylinder l l is so located and timed with relation to the cutting. cylinders that the shortest sheets are received first upon the collecting cylinder and the next longer ones superposed upon them, and so on until the product of one revolution of the cutting cylinders is superposed and associated upon the collecting cylinder with the narrowest sheets, measured in a direction transverse to the proposed fold, upon the inside and the widest ones upon the outside. As soon as the collecting cylinder has superposed the product of one revolution of the cutting cylinders the sheetsare released and forwarded by suitable tapes as 1718, traveling in the direction indicated by the arrow in Fig. 1, against a stop 19. As is best shown in Figs. 1 and Q'this stop has its bearing surface beveled to correspond to the slope produced by the even arrange ment upon one another of the progressive varying of the diameter of theshc'ets. In Figs. 1 and 2 the dimensions both as to the differences in width of the superposed sheets and the bevel of the stop are exaggerated for clearness of illustration. The sheets are brought against the stop 19 in proper relation to folding rollers 20 between which they are folded by a suitable reciprocating folding knife as 21 which is operated in any i well-known way not shown. The sheets thus folded centrally may be delivered in any appropriate manner, as by S-fly 22 and slow moving tapes 23, and when folded they will assume the form shown in Fig. 3.

V'hile Ihave illustrated my apparazus as operating upon: a single web this is only done for convenience as it is obvious that several superposed webs may be operated upon in the same manner as if a single web were used. In this case, of course, the ultimate pile before folding will consist of a series of groups of sheets composed each of several sheets of the same width, but with the sheets'of each group progressively diminishing in diameter from the bottom to the top of. the pile This it is obvious can be done without materially altering the shape shown in Fig. 3 if the webs are only.

a few in number and of thin :paper. Of course, it will be readily understood that, as suggested, the number of knives on the cut ting cylinders may be changed which will be accompanied by a corresponding change in theoperation of the collecting cylinder which will be well understood and need not be further enlarged upon here.

3V hat I claim as my invention and desire to secure by Letters Patent is 1. In combination, mechanism for severing a web into a plurality of sheets of pro gressively different width, mechanism for associating said sheets in register into a pile, having: the wider sheets on one surface of the pile and the narrower sheets on the other, a stop having a beveled bearing surface corresponding in slope with the progressively diminishing dimension of the sheets, and means for forwarding said pile of sheets against said stop.

2. In combination, means for severing a web or webs into a plurality of sheets of progressively different width transversely of the proposed fold, means for associating said sheets in register into a pile, having the wider sheets on the outside and the narrower sheets on the inside with reference to the proposed fold, a stop having a beveled hear SAMUEL G.
